Abstract (en)
[origin: WO2013176603A2] Embodiments herein relate to a method in a radio base station (12) for performing thermal noise power floor estimation in a radio communications network (1). The radio base station (12) computes table entries for a table for a transcendental function evaluation, which table is of minimized size with a range of table entries defined by a smallest table entry, a largest table entry, and a number of table entries. The radio base station (12) further estimates a thermal noise power floor by performing a transcendental function evaluation in computing a product representing a cumulative probability function,which cumulative probability function is related to the thermal noise power floor. The transcendental function evaluation is performed by using table look ups of the table with the computed table entries.
